Description of problem:
rpc.mountd can be reproducably killed on our server by trying to mount
a directory from it (no extra mount options given on commandline).
There are lots of 'udp v4 hw csum failure' kernel messages, which might
indicate a hardware problem, but I'm not sure about that.
Version-Release number of selected component (if applicable):
Steps to Reproduce:
1. just try to mount a directory from the server
2. no extra commandline parameters given to the mount command
Actual Results: mount: RPC: Unable to receive; errno = Connection refused
Expected Results: NFS mount succeeds
The name of workstation were I try to mount the NFS directory isn't
resolvable by DNs, if that matters.
That's quite bad...
When I use a DNS resolvable IP on the same workstation, the mount
command works and rpc.mountd doesn't segfault.
